Low for extent and clearance of low cloud. Low for timings of duration of rain bands on Thursday and Friday.
Dry with clear periods.
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult to follow accurately.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Dry with some patchy low cloud on the hills.

Dry throughout the day. Some mist and fog banks in the glens at first, but this should clear by mid-morning. Some cloud likely to persist across the east of the region, notably the Trossachs. Best of the brightest weather towards the west coast.
40% at first, with cloud likely to be extensive down to 300 to 600 metres. Western most ranges of Mull and Lochaber likely to see the clearest weather to start the day and enjoy the best of the cloud free summits right through the day. Increasing to 70% by afternoon but cloud down to 650 metres likely to linger across the Trossachs, Kintyre, Arran and Ben Vorlich.
Rather hazy at best at all levels with distant ridges indistinct.
Cloud may prove stubborn to lift off the tops of the Trossachs and Arran. Note risk of gales by evening above 900 metres.
Little change, early mist and low cloud lifting but cloud may be reluctant to lift off the summits in the Trossachs. Otherwise dry for daylight hours, but persistent rain spreading northeast in the evening. Windy with strong southeasterly winds, gales on the tops.
Rather hazy again, becoming poor in rain by evening.
40% in the morning with cloud down to 500 to 600 metres. Improving 60% in the afternoon, although cloud may linger around 600 metres across the Trossachs.
Southeasterly 30 mph gust 50 mph
